Clinton backs Japan over island dispute - Australia Network News - ABC News (Australian Broadcasting Corporation) The US Secretary of State, Hillary Clinton, has issued a veiled warning to China not to challenge Japan's control of disputed islands in the East China Sea. Amid signs that China is testing control over the virtually uninhabited islands, Ms Clinton said the area was under Japan's control and hence protected under a US security treaty with Tokyo. "We oppose any unilateral actions that would seek to undermine Japanese administration," she said. Clinton did not mention Beijing directly in the warning, but said: "We want to see China and Japan resolve this matter peacefully through dialogue." "We do not want to see any action taken by anyone that could raise tensions or result in miscalculation that would undermine the peace, security and economic growth in this region," Ms Clinton said. China has repeatedly criticised the US position.
